► Fig.1:

1. Switch

Before plugging in the tool, always check to see that the tool is switched off.

To start the tool, press the " I " side of the switch. To stop the tool, press the " O " side of the switch.

ASSEMBLY

Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

Installing or removing abrasive paper

► Fig.2

Open the paper clamp by raising on the lever to release from the locking port and then Insert the paper end into the clamping part, aligning the paper edges even and parallel with the sides of the base. (Bending the paper beforehand makes attachment easier). Once the paper is in place, return the lever to its original position.

► Fig.3

Repeat the same process for the other end of the base, maintaining the proper paper tension. After inserting the paper, make sure the clamping part hold it securely. Otherwise the paper will be loose and subject to slippage, resulting in uneven sanding operation.

► Fig.4:

1. Punch plate
2. Sandpaper
3. Guide

When using the dust bag, make holes in the abrasive paper using the punch plate as follows:

1. Set the tool upside down.
2. Place the punch plate over the abrasive paper so that the bent sides of the punch plate are flush with the paper edges.
3. Press the punch plate to make holes in the abrasive paper.

Be sure to remove the punch plate before operating the tool.

2. Base

1. Set the tool upside down so that the pad is on top.
2. Position the sandpaper to fit the shape of the base. Be sure to align the holes on the sandpaper with the holes on the pad (the dust will be sucked into these holes; it is therefore important to leave them open).
3. Press the paper firmly over the pad.

To remove the sandpaper:

1. Set the tool upside down so that the sandpaper is on top.
2. Grasping one corner of the sandpaper, peel it from the pad.

NOTE:

• If the sandpaper is in good condition, save it for further use.

Dust bag (accessory)

► Fig.6:

1. Dust bag

The use of the dust bag makes sanding operations clean and dust collection easy. To attach the dust bag, fit the bag's entry port onto the dust spout on the tool. Make sure that the hole in the bag's entry port is just over the pimple-like protrusion on the dust spout. For the best results, empty the dust bag when it becomes approximately half full, tapping it lightly to remove as much dust as possible.

OPERATION

Sanding operation

► Fig.15

Never run the tool without the abrasive paper. You may seriously damage the pad. Never force the tool. Excessive pressure may decrease the sanding efficiency, damage the abrasive paper and/or shorten tool life.

Hold the tool firmly. Turn the tool on and wait until it attains full speed. Then gently place the tool on the workpiece surface. A finishing sander is generally used to remove only a small amount of material at a time. Since the quality of the surface is more important than the amount of stock removed, do not bear down on the tool. Keep the base flush with the workpiece at all times.

MAINTENANCE

Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance. Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

To maintain product SAFETY and RELIABILITY, repairs, carbon brush inspection and replacement, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
